澳门六合彩历史记录 Receives NIH Grant to Develop Esophageal Cancer Stent
A bioengineer at 澳门六合彩历史记录 will develop a novel biodegradable polymer stent that will be designed to prevent complications while at the same time serving as a drug delivery system for esophageal cancer therapy.
Yunqing (Kevin) Kang, Ph.D., in 澳门六合彩历史记录鈥檚 Department of Ocean and Mechanical Engineering, and his team will use a special 3D printing technique to develop the tissue-engineered stent for esophageal cancer using biodegradable elastomeric polymer materials.
Esophageal cancer is the eighth most common form of cancer worldwide and treatment of this disease continues to be a major medical challenge. Despite improvements in surgical techniques, 50 to 60 percent of patients with esophageal cancer are not suitable for surgery, because of late tumor detection or metastases that cannot be removed with surgery.
The gold standard for treating inoperable esophageal cancer patients is a surgically implanted metal mesh stent, which causes a number of complications such as bleeding, chest pain, perforation, and tumor ingrowth.聽聽
A bioengineer in the College of Engineering and Computer Science at 澳门六合彩历史记录 has received a $141,743 grant from the National Cancer Institute of the National Institutes of Health to develop a novel biodegradable polymer stent that will be designed to prevent complications while at the same time serving as a drug delivery system for esophageal cancer therapy. Stents used by surgeons today are composed of metallic wires and are unable to carry and deliver anti-cancer drugs to treat esophageal tumors and prevent tumor tissue ingrowth.
鈥淐urrently, there are no stents that are available in a clinical setting that have the ability of preventing or decreasing the complications, and at the same time providing the capability of delivering cancer therapy drugs,鈥 said Yunqing (Kevin) Kang, Ph.D., principal investigator and assistant professor of biomaterials and regenerative medicine in 澳门六合彩历史记录鈥檚 Department of Ocean and Mechanical Engineering.
Kang and his team will use a special 3D printing technique to develop the tissue-engineered stent using biodegradable elastomeric polymer materials that will make it sufficiently rigid yet flexible enough to expand and contract with the esophagus. This new stent, which will mechanically open the esophagus, also will release the anti-cancer drug paclitaxel (PTX) to locally treat esophageal cancer.
鈥淏ecause our materials will be made from biodegradable polymer, they will dissolve and disappear after the stent is surgically placed into the patient鈥檚 esophagus,鈥 said Kang. 鈥淥nce treatment is completed, it won鈥檛 be necessary for the surgeon to remove the stent, making the process and treatment much more comfortable for the patient.鈥 聽
According to the American Cancer Society, approximately 16,980 new esophageal cancer cases were diagnosed in 2015. The disease is three to four times more common among men than among women, and the lifetime risk of the disease in the U.S. is 1 in 125.
鈥淒r. Kang鈥檚 technology is a game changer for how esophageal cancer could be treated in the future,鈥 said Mohammad Ilyas, Ph.D., dean of 澳门六合彩历史记录鈥檚 College of Engineering and Computer Science. 鈥淭he physiochemical, drug-release and biocompatibility properties of this stent could have a wider impact on the treatment of esophageal cancer and the need for tissue-engineered stents for esophagus regeneration after surgical removal.鈥
Kang joined the College of Engineering and Computer Science in August 2014 to establish the 澳门六合彩历史记录 Kang Biomaterials Laboratory. He has spent his career as a bone tissue engineer, merging his expertise in tissue engineering and cancer drug delivery systems. Kang鈥檚 laboratory is focused on developing functional biomaterials for applications of bone tissue regeneration and drug delivery system.
鈥淒r. Kang is an outstanding addition to our department and to the existing cancer research scientists at 澳门六合彩历史记录. We expect that Dr. Kang鈥檚 state-of-the-art approach in the treatment of esophageal cancer will help our university emerge as a leader in the treatment of a variety of cancers through tissue engineering approaches,鈥 said Javad Hashemi, Ph.D., chair and professor of 澳门六合彩历史记录鈥檚 Department of Ocean and Mechanical Engineering.
